22MnB5 Hot Stamping Boron Steel Coil 1.5-3.5mm Pickled Oiled Press Hardening 1500MPa B Pillar
منتوج وصف
The 22MnB5 hot stamping boron steel coil is a dedicated press hardening grade produced for lightweight automotive safety structures. Zhengde rolls this boron-manganese steel on automated hot strip mills with strict soaking and coiling temperature control, then pickles and oils the strip so blanks can be cut and formed immediately. After hot stamping and die quenching the material reaches a guaranteed 1500 MPa tensile strength, which lets carmakers replace thick high strength
